[Prior Art] Conventional inductors include metal cores, coils, adhesives, and soft-magnetic metals. The coil is wrapped around the periphery of the metal core. Lu soft magnetic metal is formed by casting mold and high temperature sintering. The adhesive is placed between the coil and the soft magnetic metal to fix the soft magnetic metal. However, in the trend of "light, thin, short, and small" electronic devices, various electronic components in electronic devices are moving toward miniaturization. Among the inductors, the softer the magnetic metal is, the more difficult it is to form, and the defect rate is also quite south. In addition, in miniaturized electronic devices, individual electronic components are becoming more and more crowded. If the inductor is to be squeezed into a small, irregularly shaped space, the designer must redesign the structure of the soft magnetic metal. As a result, it is necessary to newly develop molds to manufacture suitable soft magnetic metals. Therefore, the traditional inductors no longer pay attention to the development trend of "light, thin, * short and small". How to develop a suitable miniaturized electric salt is an important issue in the industry. Heart [new content] This creation is about an inductor 'its use of soft magnetic colloid, M332922 milk m ' conforms to the development trend of electronic devices toward "light, thin, short, small" hr according to one aspect of this creation An inductor. The inductor includes a metal core, a coil, and a soft magnetic colloid. The coil is wrapped around the metal core. A soft magnetic gel system is applied to the periphery of the coil. In order to make the above-mentioned contents of the present invention more comprehensible, the preferred embodiments are described below in detail with reference to the accompanying drawings, in which: FIG. 1A, FIG. A top view of the inductor according to the first embodiment of the present invention is shown, and FIG. 1B is a cross-sectional view taken along line BB' of the inductor 1 依照 according to FIG. 1A. The inductor 1A includes a metal core 丨1〇, a coil 120, and a soft magnetic colloid 130. The coil 120 is wrapped around the metal core 110. The soft magnetic colloid 130 is coated on the periphery of the coil 120. The soft magnetic colloid 130 includes a compound rubber 131 and a plurality of soft magnet powders 132. The glue 131 is in a colloidal state when uncured; the glue 131 is solid after curing. Soft • The magnetic particles 132 are doped in the uncured adhesive 131, and after the adhesive 131 is cured, the soft magnetic particles 132 are embedded in the cured adhesive 131. Referring to Fig. 2 and Figs. 3A to 3F, Fig. 2 is a view showing a method of manufacturing the inductor 100 according to the first embodiment, and Figs. 3A to 3F are diagrams showing the steps of Fig. 2. First, referring to FIG. 3A, the process proceeds to step S102, and the metal core 110 is provided. In the present embodiment, the metal core 110 includes a first spacer 111, a second spacer U2, and a metal post 113. The metal post 113 is connected between the second partition U1 and a second partition 112 M332922 9Z 2.. Next, please refer to Fig. 3B, in which the coil is wound in the metal pillar S1G4 of the metal core 11G. Then, refer to Fig. 3C, and the container 900 is on the periphery of the metal anger 110. There is a gap G between the tubular sleeve and the coil 120. 900 inner wall 9〇〇a Next, please refer to the 3D figure, in the soft magnetic body of the step 30. This day is recorded, not yet cured, soft magnetic particles 13, glue 131 container _ the inner wall _a ^ ^ n glue 131 - secret into the tubular and soft magnetic particles 132 line edge shown in the 1B = gap G . (The rubber material 131, wherein the material of the glue material 131 is as clear as 1 _glue), the stone yoke glue (sil = k ultraviolet light-curing glue (such as the material of the uv soft magnetic particle 132). (Μη), and the soft magnetic colloidal body alloy (Mn-Zn) and the magnetic particles of the record. ^Body gamma contains Na ~ 鄕 soft nn la after the second sun body 130 fills the gap G, the soft magnetic colloid 130 contacts _ 12G, and completely surrounds the coil 12G Peripheral. Preferably, the soft magnetic particles [the raw particles 132 are evenly distributed on the rubber material 131 0, so that the soft magnetic particles 132 are evenly distributed on the periphery of the coil 120. No. What kind of metal core 11〇, soft magnetic colloid (10) It can be smoothly coated on the periphery of the metal core 11 () and _ i2G. That is to say, the soft magnetic (10) (four) 13G is suitable for the metal core 11 各 of each rail inch. Then, please refer to the 3E mesh, in the step measurement, the soft magnetic softening M332922 91 2. 13 * Colloid 130. The method of curing the soft magnetic gel 130 is based on the material of the rubber ΐ 3τ. For example, if the material of the rubber 131 is UV-curable, the ultraviolet light is used. Curing soft magnetic colloid 13〇. The material of the adhesive 131 is epoxy For the grease, the soft magnetic colloid 130 is cured by heat curing. The third drawing uses a heat source crucible to cure the soft magnetic colloid 130. At this time, the soft magnetic colloid 130 can be based on the inner wall of the tubular container 9 The shape of 900a is shaped and fixed on the periphery of the coil 12〇. Among them, the glue is not required to be fixed between the soft magnetic colloid 130 and the metal core 110. This not only increases the space in which the coil 120 can be wound, but also reduces the space. Process step and material cost. That is to say, the inductor 100 can adopt a thicker coil 120 to withstand a larger current. Next, please refer to the 3F figure, in step S112, the tubular capacity is removed to 900. The inductor 100 of the first embodiment is formed. In the case where the electronic components of the circuit board become increasingly crowded and the space becomes increasingly narrow, the predetermined set area of the inductor 100 is often obstructed by adjacent electronic components to form an irregular shape. The soft magnetic colloid 130 can be formed into various shapes to facilitate setting in predetermined areas of various shapes. Taking the figures 4 to 5 as an example, the other forms of the inductors 200 and 300 are shown. In Fig. 4, the soft magnetic colloid 230 of the inductor 200 has a beveled edge 230a. In Fig. 5, the soft magnetic colloid 330 of the inductor 300 has a rectangular structure. The inductors 200 and 300 are arranged for a predetermined area. However, the shape is changed, but the inductors 200 and 300 are no longer required to be complicated and expensive, such as molding and sintering, and can be easily formed into various shapes, which not only greatly increases the flexibility of use, but also reduces the manufacturing cost. The above embodiment is also
